Planetary nebulae such as Hen 2-437 form when an ageing low-mass star — such as the Sun — reaches the final stages of life. The star swells to become a red giant, before casting off its gaseous outer layers into space. Hen 2-437 is a bipolar nebula — the material ejected by the dying star has streamed out into space to create the two icy blue lobes pictured here.
If you have never seen the International Space Station (ISS), make the most of clear skies over the next few nights. It’s capable of exceeding Venus at its brightest and visible for up to 7 minutes as it crawls across the sky in an arc from west to east. Find out when and where to see some favourable passes of this 420-tonne, 109-metre-wide spacecraft over the British Isles and Western Europe.
